AUSTRALASIA. 151 



Lake Brown and Mt. Churchman, near Lake Moore, granite was dis- 

 covered; and it occurs at intervals from Mt. Churchman, itself a granite 

 hill, to the X. end of L. Moore, thence in a ^N'.E. direction to L. Barlee, a 

 large dry salt lake. Throughout the country forming the N. boundary 

 of the supposed E. extension of this lake as far N. as Mt. Holmes, 

 granite is the prevailing rock, and is again met with further W., on 

 the W. side of Lake Monger. Great local attraction was experienced 

 on some of the hills about L. Barlee. At the most E. point reached, 

 lat. 28°41' S., and long. 122° 50' E., sandstone prevailed (? Desert 

 Sandstone), forming open spinifex desert. In the neighbourhood of 

 Mt. Singleton trap rocks occur. — 2. Explorations from Perth to Adelaide^ 

 around the Great Australian Bight. From the point at which the Ex- 

 pedition struck the S. coast at the Phillips River, as far as long. 124° E., 

 between Israelite Bay and Point Culver, granite prevails extensively ; 

 but at this point onwards to the Head of the Great Australian Bight, 

 400 miles, the country at and near the coast consists of a Tertiary lime- 

 stone, forming perpendicular cliffs 300 to 400 feet high. — 3. Explora- 

 tion from Champion Bay across tJie Desert to the Telegraph, and to 

 Adelaide. The upper waters of the Murchison flow through a granite 

 country. Mt. Hale, near the source of this river, is composed of mi- 

 caceous iron -ore and brown magnetic htematite. The Kimberley 

 Range, considered as the watershed of the Murchison, is composed of 

 very magnetic brown haematite, in places yielding a bituminous pitchy 

 substance, probably of organic origin. The banks of Kennedy Creek 

 are composed of slate, supposed to be Silurian. The general character 

 of the immense tract of country from this to the 129th meridian is a 

 gently undulating spinifex desert, composed of a light red sandstone, 

 cropping out and forming low cliffs (Tertiary Desert Sandstone). 

 Granite again makes its appearance in the Mann Ranges. There is an

 the Expedition." R. E., Jun.

 During excavations in the city of Auckland, a tree-stump was dis- 

 covered in its naturfd position, upright, with roots penetrating the 

 surrounding clay, and covered by about 25 feet of volcanic debris, con- 

 sisting of stratified beds of ooze and volcanic ash, adjacent to a volcanic 

 centre. The clay in which the roots occur rests upon Tertiary rocks, 

 and is 10 to 15 feet thick. The stump is said to bo a *' tea-tree " 

 (Manuka), and appears to have been cut by a tool. Tho author thinks 

 that it gives evidence of tho " existence of man long before tho period
